Internal linking connects pages within the same website — for example, a blog post linking to a related glossary term or service page. It helps visitors navigate, spreads ranking authority across a site, and helps search engines discover and understand the relationship between pages, a practice covered in Google Search Central (opens in new tab)’s own site structure guidance.
Why This Glossary Links So Heavily to Itself
A page that only ever gets linked to from the homepage is much harder for search engines to judge as important, while a page linked from many relevant places across a site sends a much stronger relevance and authority signal. That’s the reasoning behind linking glossary terms to related terms, blog posts, and comparisons rather than leaving each page isolated.
The anchor text used for the link matters too — a link that says "how NFC works" tells a search engine more about the destination page than a generic "click here" ever could.
It also directly benefits visitors, since a reader curious about a related term or topic can follow the thread naturally instead of leaving the site to search for it elsewhere.
People also ask
How many internal links should a page have?
There is no fixed number — link naturally wherever a reference genuinely helps the reader, typically a handful of relevant internal links per long-form page.
